BATTERY-CELL.

Application led Jane 11,

drawings and the characters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawingsconstitute part of this application, and represent, in

Figure 1 a side view partly insection of a battery cell constructed inaccordance with my invention. Fig. 2 a planview with the top and gridsor plates removed. Fig. 3 a sectional view on the line a-b of Fig. '1.`Fig. 4 an underside view ofthe bottom plug. Fig. 5 an'insideyiew of theclosing,r cap.

This inventief;L relates to an improvement in battery cells particularlybatteries 'of the type employing plates suspended in the cells andcommonly known as storage batteries. In the use of. these batteries asediment collects in the bottom of the 'cell Which when in suflicientamount will short circuit the various' plates. These batteries must,therey plate which Willnot interfere With the perfect {iushing of thecell. y

Afurther object of the invention is to provide means for firmly closingIthe flushing outletat the bottom of thecell and making a double seal;and the invention `consists in the construction hereinafter describedand particularly recited in the claims. lh carrying out my invention, Iemploy a cell '2 of thel desired shape, usually rectangular in crosssection, and near the bottom I provide transverse bars ,or arches 3 and4, the under faces of the ends 5 and 6 being bev` el-ed and curveddownward toward the bottom Specicaton of Lettersatent.

of the cell so as to provide a firm support, these arches being formedintegral'with the cell. In the bottom of the cell is a central threadedopeningl 7, and around this opening is a necr externally threaded.Inserted into the bottom of the threaded openingr 7 is a threaded vplug'9 formed with a central an'- gular recess 10 to receive a wrench bywhich the' plug may be screwed into the opening 7. Over the neck 8 Isecure a cap 11 which' contains a rubber disk 12Which cornes to abearing on the outer end of .the neck 8 and end of the plug 9 so as toform aperfect double Water-tight closure for'the bottom of the cell. Atthe top of the cell is an inlet 13 through which liquid may be passed"13 and the entire inner surfaceof the cell thoroughlyfwashed, and onaccount of the character of the supporting; bridges 3 and 4 no pocketsare formed whichprevent the perfect circulation of Water around thebottom of the 'cell and so that all particles of sediment can beremoved. It .will be under,

stood that the usual battery grids or plates 14 rest upon the upperledges of the arches 3 .and 4, and as.the upper edges of these archesare rounded the.possibility of short- 'circuiting between the plates isreduced to the minimum.- In 'Washing' the cells it is unnecessary todisconnect the lead-connec# tions' between the batterles or remove theplates from the cells.

AI claim 1f A battery cell provided near its bot'- l tom withintegraltransverse arches upon which batteryrplates may rest.

2. A battery cell formed near its bottom with 'integral .transversearches the main portions of which stand above the bottom ofl the-cell.said cell provided at'its upper end with an inlet opening and in itsbottom with y y a central threaded opening, an externally threadedcollar around saidv opening, a

threaded plug adapted to b e entered into said central opening, athreaded closure cap applied to said neck and a sealing disk Within saidcap. I
